A milligram (mg) is a unit of mass in the metric system, equal to one-thousandth of a gram (1 mg = 0.001 g). It's one of the smallest standard units used in everyday measurements and is essential when dealing with very light weights. Milligrams are especially useful for measuring things that are too small to be weighed in grams—like medication doses, vitamins, or trace ingredients in scientific experiments.
The word "milligram" is derived from Latin roots: milli-, meaning "one-thousandth," and gramma meaning "a small weight." It became part of the International System of Units (SI) as countries adopted metric standards for more precise and consistent measurements.
How is the Milligram Used: The milligram plays a vital role in fields where accuracy matters most. Because it's a tiny measurement, even slight errors can affect results—especially in health and science.
A tonne, also known as a metric ton, is a unit of mass equal to 1,000 kilograms or approximately 2,204.62 pounds. It's the standard ton used in most countries that follow the metric system, including Europe, Asia, Australia, and many parts of Africa. Unlike the US ton (short ton, 2,000 lbs) or the UK imperial ton (long ton, 2,240 lbs), the tonne is based on powers of ten, making it more consistent with the metric system. It's used in industries where large-scale weight measurement is common, such as shipping, agriculture, and waste management.
The tonne originated in France in the 18th century as part of the adoption of the metric system. The word comes from the French word "tonneau," which referred to a large cask used for transporting wine or oil.
It became widely accepted across Europe and eventually by the International System of Units (SI). Today, it's the standard unit for mass in global trade, environmental reporting, and scientific documentation.
How is the Tonne Used: The tonne is used to measure very large weights where smaller units like kilograms or pounds would be impractical. You'll find it commonly used in:
1 mg = 0 t
Let’s say you want to convert 100 mg to t.
Using the formula:
100 × 0 = 0 t
So, 100 mg is approximately 0 t.
